Description
Die Erfindung bezieht sich auf Schaltwerke mit stelzenförmigen Klemmkörpern zwischen kreisförmigen und konzentrischen Klemmbahnen, bei denen die Klemmkörper mit zwei kreisförmigen Exzentrizitäten versehen sind, deren Mittelpunkte auf der Stelzenlängsachse liegen.The invention relates to switching mechanisms with stilt-shaped clamping bodies between circular and concentric clamping tracks, in which the clamping bodies with two circular eccentricities are provided, the centers of which are on the longitudinal axis of the stilts lie.
Das Neue besteht darin, daß die mit Spiel im Gehäuse der treibenden oder getriebenen to Welle um ihre Schwenkachse drehbar gelagerten Klemmkörper zur Umkehr des Drehsinns der getriebenen Welle um etwa i68° um -ihre Achsen gedreht werden. Diese Drehung der Klemmkörper erfolgt mittels einer gemeinsamen Vorrichtung. Die Klemmkörper werden mit Schraubenfedern in ihrer Eingriffslage gehalten.The novelty consists in the fact that those with play in the housing of the driving or driven to shaft rotatably mounted sprags around its pivot axis to reverse the direction of rotation of the driven shaft can be rotated about i68 ° around its axes. This twist the clamping body takes place by means of a common device. The sprags are in their with coil springs Position of engagement held.
Die Erfindung ist in zwei Abbildungen dargestellt, und zwar in Abb. 1 zur Hälfte offen, also ohne Deckscheibe b, und in Abb. 2 zur Hälfte im Schnitt A-B. The invention is shown in two figures, namely in Fig. 1 half open, that is, without a cover plate b, and in Fig. 2 half in section AB.
Das Schaltwerk besteht aus dem Gehäuse α, welches durch die Deckscheibe b, die mittels versenkter Schrauben c an das Ge- *5 häuse angeschraubt ist, geschlossen wird.The switching mechanism consists of the housing α, which is closed by the cover plate b, which is screwed to the housing by means of countersunk screws c.
Die Klemmrollen d sind einerseits in dem Gehäuse a, andererseits in der Deckscheibe b mit Spiel gelagert. Auf den Achsen der Klemmrollen d sind Zahnkreuze e aufgeschraubt. Die Zähne, dieser Kreuze haben etwas Spiel in den Zähnen des Ringes g. Dieser Ring g ist auf der Deckscheibe b drehbar und durch die Bolzen h in Schlitzen geführt. Die Drehung des Ringes g wird an dem Nocken / eingeleitet. Durch die Federn i werden die Klemmrollen d in der gezeichneten Stellung gehalten. Soll nun das Schaltwerk nach der anderen Richtung als durch den Pfeil angegeben ist, wirken, so werden die Klemmrollen d mittels des gezahnten Ringes g und der Kreuze e um etwa eine halbe Umdrehung gedreht. Dann wirken die Federn i auf der andern Seite, und somit wird die Schaltrichtung des Freilaufes gewechselt. Der Scheibenring Ie, der mit der Welle I verschraubt ist, verhindert zugleich, daß sich das Gehäuse auf der Welle I axial verschiebt. Das Schaltwerk kann außer für Drehbewegungen auch für geradlinige verwendet werden. Die Klemmbahnen werden dann zu geradlinigen. The pinch rollers d are mounted on the one hand in the housing a, on the other hand in the cover plate b with play. Toothed crosses e are screwed onto the axes of the pinch rollers d . The teeth on these crosses have some play in the teeth of the ring g. This ring g can be rotated on the cover disk b and is guided in slots by the bolts h. The rotation of the ring g is initiated at the cam /. The clamping rollers d are held in the position shown by the springs i. If the switching mechanism is to act in the other direction than indicated by the arrow, the pinch rollers d are rotated by about half a turn by means of the toothed ring g and the crosses e. Then the springs i act on the other side, and thus the switching direction of the freewheel is changed. The disk ring Ie, which is screwed to the shaft I , also prevents the housing from moving axially on the shaft I. The derailleur can be used not only for rotary movements but also for linear movements. The clamping tracks then become straight.
